ACL managing director Lyle Shelton said bullying children for any reason was unacceptable but the Safe Schools program went way beyond the purview of an anti-bullying program.

"Parents expect their children to be safe at school but encouraging boys who identify as girls to use the girls bathrooms and share school camp accommodation is not the way to do this," Mr Shelton said.

Mr Shelton said many parliamentarians were unaware of what Safe Schools promotes to children as young as four.

"Telling four-year-olds that no one can tell you what gender you are is confusing and indoctrination in contested and dangerous gender theory.

"Safe Schools tells children they must have access to the Minus 18 website which instructs girls in chest binding so their breasts are flattened and penis tucking for boys."

Since marriage was redefined in countries like Ireland and Canada, programs like Safe Schools had become mandatory.

The Victorian Government plans to make Safe Schools mandatory from 2018.

"Many people are asking questions about where rainbow ideology is taking our politics.

"The Government should immediately pay out its contract with the program providers," Mr Shelton said.

"The break fee would be a small price to pay to ensure all children could be safe at school."
